Installing FireDAC 8 for Delpi 2007
Posted by jpluimers on 2015/08/19
Installing FireDAC 8 for Delpi 2007
Installation
- Obtain
29458_firedac_xe4_update_2_for_rad_studio_delphi_c_ent_ult_arch.zipfrom a registered Delphi XE4 or higher license: http://cc.embarcadero.com/item/29458: - Extract it into
FireDAC_8.0.5.3365.exe. - Run
FireDAC_8.0.5.3365.exewith the/showideparameter as described in http://support.embarcadero.com/article/42970: FireDAC_8.0.5.3365.exe /showide- (When not running as Administrator: elevate to Administrator)
- Welcome screen: press
next - License screen: accept, then press
next - Destination selection screen: keep
C:\Program Files (x86)\Embarcadero\FireDAC, then pressnext - Select components screen: keep the selection (Full installation), then press
next - Select IDEs screen: choose Delphi 2007 (but not Delphi 2006), then press
next - Select Demo Databases screen: keep the settings (do not choose
Interbase / Firebird serveras then you have to provide the credentials for the server), then pressnext - Start menu screen: keep
Embarcadero FireDAC, then pressnext - Ready to install screen: press
install - After installation: press
finish, then read thereadme- or later browse to <file:///C:/Program%20Files%20(x86)/Embarcadero/FireDAC/Readme.html>
- That’s what actually tells you:
The installer automatically installs FireDAC in the Delphi XE4 and C++ Builder XE4 IDEs. For older versions of the IDEs, you can run the installer with the /SHOWIDE command line parameter.
After installation
To fix this when starting Delphi:
[Window Title] Error [Content] Can't load package C:\Users\Public\Documents\RAD Studio\5.0\Bpl\AnyDAC_Dcl_D11.bpl. The specified module could not be found. Do you want to attempt to load this package the next time a project is loaded? [Yes] [No]
The actual BPL sometimes is in C:\Users\<username>\AppData\Local\Documents\RAD Studio\5.0\Bpl\AnyDAC_Dcl_D11.bpl
The cause is that the BPL gets loaded from %BDSCOMMONDIR% which on some systems points to
%PUBLIC%\Documents\RAD Studio\5.0
and on others points to
%LOCALAPPDATA%\Documents\RAD Studio\5.0
This seems to be the case on machines where more different Windows users are using Delphi.
The installer does not fully recognize this distinction, so copies the BPL to %LOCALAPPDATA%\Documents\RAD Studio\5.0\Bpl and registers it as being in %PUBLIC%\Documents\RAD Studio\5.0\Bpl.
On these machines there is a difference between the definition of BDSCOMMONDIR in these registry keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment- points to
C:\Users\Public\Documents\RAD Studio\5.0
- points to
HKEY_CURRENT_USER\Environment- points to
C:\Users\<username>\AppData\Local\Documents\RAD Studio\5.0
- points to
Solution
reg delete "HKCU\Software\Borland\BDS\5.0\Known Packages" /v "%PUBLIC%\Documents\RAD Studio\5.0\Bpl\AnyDAC_Dcl_D11.bpl" /f reg add "HKCU\Software\Borland\BDS\5.0\Known Packages" /v "%BDSCOMMONDIR%\Bpl\AnyDAC_Dcl_D11.bpl" /t REG_SZ /d "Embarcadero FireDAC Components" /f

Fuzzing in addition to Unit Tests – via: David Millington G+
Posted by jpluimers on 2015/08/11
I need to give this link from Jonathan Lange which was shared by David Millington some thought:
There they add fuzzers to help testing an ADT: in this case an Abstract Data Type in the form of a red-black tree.
And then see if it can be added to DUnit and NUnit or MSTest/VSTest in some way.
In the original post by Jonathan Lange, an important remark was made by Eric Castelijn:
… the downside being that having non deterministic tests means having test failures that are hard to repeat
…
When fuzzing multiple or composite values, the chances that you will hit interesting edge cases semi-reliably will drop dramatically, in my experience

Delphi: turn off column or line block selection mode – via: Default IDE Shortcut Keys; Delphi Programming
Posted by jpluimers on 2015/07/30
The Default IDE Shortcut Keys – Delphi Programming was a good starting point to find out how to disable column or line blocks.
Since the table there is incomplete (even the Embarcadero documentation is wrong as some shortcuts can turn on and off a mode), here are the relevant shortcuts keys:
| Ctrl + O + C | Turns on/off |
Delphi 5 and up |
| Ctrl + O + K | Turns on/off block selection mode | Delphi 5 and up |
| Ctrl + O + L | Selects current line (and turns off block selection mode) | Delphi 5 and up |
This is especially useful when the block selection is stuck (this happens every now and then: it’s a known bug).

Jon Skeet’s speech “Back to basics” is really a good watch – via Jørn Einar Angeltveit G+
Posted by jpluimers on 2015/07/15
Thanks [Wayback] Jørn Einar Angeltveit for sharing this a while ago:
A session by Jon Skeet and Tony the Pony (which has strong teeth) presented during the Polish DevDay 2013 in Kraków, Poland.
[Wayback] +Jon Skeet’s speech [Wayback] “Back to basics” is really a good watch.
In a funny way, he explains why the simplest fundamentals of computer software text, dates and numbers can cause some real headache for the programmer…
In case you didn’t know: Jon Skeet is “Chuck Norris” on [Wayback] stackoverflow.com:
The subtitle is “the mess we’ve made of our fundamental data types”.
Some of the topics covered:

Interesting. Not only about Delphi history, as Chuck has done so much more nice things.

20 resources on migrating to Unicode with Delphi | Software on a String
Posted by jpluimers on 2015/07/08
Great post by Marjan Venema when you need to migrate your old Delphi programs to the modern Delphi world: [Wayback] 20 resources on migrating to Unicode with Delphi | Software on a String.
I’m glad that some of the links overlap with what I posted and presented in the past at:
- Some Unicode links.
- Unicode at wiert.me.
- Video + Q&A transcript of Using Unicode and Other Encodings in your Programs.
Well done Marjan!

Windows Kernel object names are optional. Don’t give them a name unless you intend them to be shared. (via: The Old New Thing)

Very interesting:

via: [WayBack] You can name your car, and you can name your kernel objects, but there is a qualitative difference between the two – The Old New Thing – Site Home – MSDN Blogs.

Scala programming language and Venkat Subramaniam videos
Posted by jpluimers on 2015/06/30
A long while ago, someone (it was too long ago, so I sincerely forgot who, it probably was in the JBuilder era) told me that I should try out Ruby and Scala.
I did take a short look at Ruby back then, but since Ruby was so focussed on Web Development, and my heart really wasn’t there, postponed it to the times that the Web would be hot for me.
Then I should have taken a look at Scala (which compiles to Java bytecode), but since I abandoned Java (JBuilder wasn’t nice, Java programming was slow and modern IDEs like IntelliJ IDEA and Eclipse weren’t there yet).
Now that I’ve done truckloads of work in the .NET and Delphi world (including domain specific languages and Pascal based products), I bumped into these Scala videos by Venkat Subramaniam:
Boy, I should have taken a look earlier: like Delphi and C# it is a statically typed compiled language, but it is on steroids.
Yes, I know it leans on the Java bytecode as a run-time platform, but so does the Android SDK as one of the Java Platforms. Contrary Ruby, which with IronRuby runs on .NET and RubyMotion runs Mac and iOS, Scala does not run on the .NET platform any more.
Given the witty way of presenting I’m surely going to follow Venkat Subramaniam and watch some of his other videos too.
Shortly after watching the above I bumped into this video by Steve Yegge (Google): Dynamic Languages Strike Back – YouTube.
